.To all whoinl t may concern:

Be it known that I, HENRY M. REIGHEN- BACH, a citizen of the United States, residing at New York, in the county of New York and paratus.

State of New York, have invented certain new and useful Improvements in Carbureters; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same. j My invention relates to improvements in devices for the storage of liquid fuel, and the 4supplying of carbureted air to internal combustion engines, the storage tank acting as a combined storage tank and carbureter,

there being no free vfluid in the storage tank,

thereby eliminating the danger of leakage of such free iiuid in the vehicle, vessel or car in which the engine is used. The fuel is su f plied to the tank at intervals, and the supp y is stored at some point separate from the ap- The tanks are of such ca acity that they will hold by absorption a su 'cient quantity of fuel for trips away from the basic supply-from five to fifty gallons, or

'more, as is necessary.

The object of my invention is to roduce a erfectly safe carbureter, in whic all the el is contained ina mass of absorbent material, which carbureter may be connected with a source of supply at intervals.

Other objects are to provide a carbureter in which volatilization 1s readily effected, in which means for varying the amount of fuel used, is provided, and in which provisionis made to compensate for the refrigeration Vcaused by the volatilization of the fuel.

With these objects in view'my invention ...consists in the construction and combinations of parts as hereinafter described and claimed. r i

In the accom anying drawings Figure 1 is a longitudinal) vertical section of my improved carbureter. Fig. 2 is a horizontal cross section thereof taken just below the top. Fig. 3 is an end elevation partly broken away, Fig. 4 shows in detail the means for distributing the fuel. Fig. 5is side view of the carbureter and the tank for filling the same.

a, represents the main casing preferably made of metal, across which near the top thereof extends a metal late b having Spring edges c which hold t e same in posilink s.

tion. This plate isperforated `as shown at d, and around each perforationfthe edges of the plate are turned upwardly, asshown at e to prevent the gasolene or otherl'fuel from Arunning down through these perforations. Near the outer edges of two sides of the plate b it is provided with perforations f through which the fuel drips down through the carburetir casing. a

Parallel to the plate l) are a series of plates g similar in construction to the plate eX- cept that they extend less than half way across the casing a, and are provided en the the wall t, the outer edges c in connection with the edges 7L serving to holdlthe plates in position. The construction is thesaine on oth Vsides of the carbureter, leaving an open chamber between the walls h.

Below the plate l), and between the plates g, are located a number of layers of absorbent materiali, which receive the liquid fuel as it drips through the perforations f on the outside edgesof the plates and conducts it t0- ward the center. The plates and the layers of absorbent material are all perforated, the perforations being located in line with each other so that the passages e extend from` nearly the top to the bottom of the casing c.

Any suitable absorbent material may be used, but I prefer to use dry wood felt.

lt' represents the air inlet pi 3e, which is connected to the external air and is provided with a valve m. This pipe 7c enters one end of the chamber a and passes nearly the whole length thereof, as shown 1n Fig. l, being provided with a number of perforations 'n through which the oil is discharged onto the top plate b, which plate has a central bead o to direct the liquid fuel to either side of the carbureter casing. The fuel inlet pipe delivers directly into the air pipe 7c, as hereinafter described.

p represents the outlet pi e -for the earbureted air which is provide with a series of perforations g. This pipe leads to the engine and is controlled by a valve r o j erated by the This valve is adj ustab e by means of the set screwlt.

u represents apipe connected with the eX- ternal air which joins the pipe p in a union joint e, which serves as a mixing chamber. The pipe u is provided with a valve w.

By the means described, if the carbureted air in the pipe p contains too large a portion 'inside with bent edges h which rest against IIO of fuel additional air may be mixed therewith to make the proper mixture. The valve w is operable by a handle and this handle, by means of a lever y and link e, is connected to the link s, so that the movement ofthe handle :l: simultaneously operates the valves r and w.

1 represents the exhaust pipe leading from the engine. Connected to this pipe are pipes 3 and 4 which pass into the chamber 5 between the Walls fi, the ipes 3 and 4 and the chamber 5 forming a y-pass, whereby the whole or a portion of the exhaust gases may be admitted into the inner part ofl the carbureterl to supply heat thereto to. compensate for the loss of heat caused by the evaporation of thefuel.

The pipe 1 is rovided with a valve 6, the movement of wiich causes a greater or less amount of the exhaust gases to pass through the carbureter, or permits them to pass freely through the -pipe 1. This valve is operated by a handle 8 which is connected by a link 7 with the link z, so that the valve 6 is operated simultaneously with the valves 1 and 'w by the movement of the single lever lEach of the valves 1", w and 6 is provided witha set screw, such as t, so that they may be adjusted relatively to each other. In winter, for example, it is desirable that a larger roportion of the exhaust should pass throug i the carbureter, than in summer, and furthermore, under certain conditions of weather, or with certain kinds of fuel, diflerent quantities of air must be drawn in through the pipe u. All this is determined by experiment and the set screws t adjusted, and after this adjustment has been made a movement of the lever :c is all that is required to control the richness of the carbureted air mixture.

The heating of the carbureter may also be accom lished by means of the cooling water from t e cylinders, instead of by the exhaust gases, in which case the ipes leading the hot water from the 'cylinc er, pass into the chamber 5 and then connect with the cooler.

My improved carbureter is also provided with a safety filling device. end of the tube 7c is a fuel ipe 9 provided with a valve 10 and a funne 11. From'the bottom of the carbureting casing extends a drainage pi e 12 provided with a valve 13, and the en of this pipe is made conical. A lever 14 is used for opening or closing the valve 1 0, and a link 15 connects this lever with the lever 16, which operates the valve 13., so that the'valves 13 and 10 are opened and closed simultaneously.

17 represents a fuel supply pipe, the upper end of which is curved.

18 represents a drainage ipe having a conical topi which is adapted) to fit tightly over the end of the discharge pipe 12 of the carbureter proper. The pipes 17 and 18 are movably connected together by the fitting Entering the 20, which is rigidly attached to thepipe 18, and through which the pipe 17 slides, when drawn downward by the spring 21, which is attached at one end to the fitting 20, and at the other end to a projection 19 on the pipe 17.

Fig. 5-re resents the tank in the position to fill the cariiureter.

25 represents the tank provided with a projecting boss or fitting 22 through which the pipes 17 and 18 pass.

23 represents (in' dotted lines) a pump, having an operating handle 24 projecting up through the fitting 22, said pump delivering into the lower part of the pipe 17. The lower parts of the pipes 17 and 1S may be flexible, if desired.

One distinct feature of my invention is that the carbureter is. not directly connected to the fuel tank, but is supplied with fuel only at intervals, and this is an important feature as regards the safety of the device. Furthermore, the air in thepipes k and u is carried to a higher point than usu al so that if the fuel should volatilize too rapidly through overheating of the carbureter, it would either be condensed in these pipes or delivered to the external air. ln no case could there be an escape of carbureted air into the compartment containing the engine. This is a very valuable feature for submarine boats, passenger cars, automobiles, and all other forms of conveyances. In a submarine boat the air inlets will, of course, necessarily connect with the air inside of the boat, but in such a case a condenser coil or other pipe extension should be used to prevent any backward movement of thc` vapor from the carbureter.

Another distinct feature of my linvention is the provision of the heating chamber and the location of the same in the mass of absorbent material or in Contact therewith, and arranged to deliver heat to the plates separating and extending into the absorbent material. With the arrangement described, the liquid is delivered to the absorbent material at points remote from the heater and moves through the absorbent material in directions opposite to the flow of heat from the heater along the plates, separating the absorbent material. The result of this arrangement iS that the liquid will vaporize as it moves toward the heater, and the lighter hydrocarbons will be driven ofi' first and at points remote from the heater, while the heavier hydrocarbons will move along until they reach points where the temperature is so high, owing to the proximity of the heater, that they also will be vaporized.

One of the chief objections to many of the carbureters now .in use is that they cannot be used without considerable danger of explosions, and it is now regarded as highly desirable, and even indispensable, to have the ICO safety factor of carbureters very high.

This advantage is fully secured by the present invention.
